Today we will be working on a China G41 Motherboard with no Display Case.
Initially we found that there is no codding on diagnostic card and No VCore voltage.
So Removed a Protection Mosfet which was connected in Enable signal track.
Now, we were having VCore voltage and codding on diagnostic card too but board was turning off as soon as it was powered .
So after lot of search we found that Northbridge is Short w.r.t Ground.
It's No fix but we can get know how to diagnose motherboard and find missing voltage then trace it and fix problem.
